CAROLINE Buchanan won't be satisfied with anything less than gold in Rio.
The 25-year-old BMX superstar (pictured) had hoped to already be an Olympic champion - and looked on track in London.
She qualified fastest for the final, but mistimed her start in the ride for gold. In the fast and furious competition of BMX riding, the start is the most important aspect.
Buchanan never stood a chance after having to play catch-up and was forced to settle for fifth place.
After taking six months to regroup, the Canberra local will again go into an Olympics as the favourite as the world's top-ranked rider.
"Coming into Rio, knowing what to expect and having been there before and having been through the qualification process, I am now a lot calmer and it has been ticking the boxes of planning and preparation,” Buchanan said. "The goal is for Rio redemption - to win gold.
"The toughest competitor is always yourself. I battled my own mindset and nerves got the better of me in London. Four years on with three more world titles and five more World Cup wins I am a different athlete coming into Rio.”
Colombia's Mariana Pajon, who won gold in London, will again be a rival to watch after beating Buchanan for gold at the world championships in Colombia earlier this year.
